Basically, alcoholics take cocaine or crack so they can keep drinking and not pass out. It's also a bit of a hangover cure.

Crack CAN lead to weight gain IF you have enough money for food, coming off crack crashes your blood sugar, making you binge. Sadly most crack addicts don't have enough money for food so they drop weight.

I feel like I want to respond to this even if I don't know what you're trying to say. My response, despite that lack of understanding, is this: Yeah, only phony sissy men love p---- so much they want to bury their faces in it.
